Letters Patent No. 99,405, dated February 1, 1870; antedated January 28, 1870.

IMPROVED CARRIAGE-HUB.

- The Schedue refen'ed to in these Letters Patent and making part of the same i 'To all whom it may concern:

Be it known that I, JOHN P. CHANDLER, of `Wilton, in the county of Franklin, and State of Maine, have invented a new and improved Carriage-Hub; and I do hereby 'declare that the following is a full and exact description of the same.

The nature of my invention consists in a malleable iron skeIeton-hub, made and constructed in the following manner:

I have as many mortises as I desir'e spokes in the wheel. These motises are constructed in a conical form. The mo'tises otherwise are the same as in wooden hubs. The depth of the skeleton to be the desired length of the tenon of the spoke. The outer encasements, connected by the partitionsbetween the mortises, are about one-quarte* of an inch thick, or more, according to the size of the wheel and strength required, and protrude outwardly each way. snflicient to form the whole hub.

I have two headings, one at the small end, the other at the large end of the hub. The heading'at the small end of the hub is cast, together with the hub, in such a way that it leaves the hub projecting out far enough to form a band, as on a common hub. This heading is of sufilcient thickness,` has a hole in the centre, conical in form, to receive the common axle-box. In this heading I have a key, to hold the axle-box in its .proper place.

The heading at the large end is cast separate, having a hole in the centre, same as in the other heading, to receive the common axle-box, and screws into the lub far enough to leave the hub projecting to form a band, as at the other end, and holds the aXle-box tight and firm. In this heading I have two small holes, in which to place a wrench, to screw it in fight.

To enable others skilled in the art to more perfectly understand my improvement, I will proceed to further describe the same as illustrated in the accompanying drawings, which constitute part of this specification, and represent, in

Figure 1, a front View of the wheel.

Figure 2, a longitudinal central section.

Figure 3, a. side View. ,i

Figure 4, a front view of the heading at the large end of the hub.

Flgure 5, a side view of the heading at the large end of the hub, with axle-box attached.

A are the encasements of the hub.

B is the heading, in the centre of which is the hole O, to receive the com mon axle-box.

D is the key in the heading, at the small end of the hub, to fasten the axle-box.

a, are the mortises, toreceive the spokes.

E is a vacuum-space between the headings.

F represents the axle-box running through the hub.

Gr are the holes, in which is placed the wrench, to screw the headings in at the large end of the hub.

By my invention I avod,.first, the necessity of using a wooden hub; second, of extra iron bands; third, the difliculty of setting the axle-box true in a wooden hub; fourth, the liability t'o shrink and swell of acom mon hub, which causes the axle-box to become loose.

The spokes, when driven into the mortses, are tight and firm, and cannot settle any further. I more securely fasten the axle-box than in any other hub. Also, this hub is lighter, more durable, and costs less than any other hub.

What I'claim as new and of my invention, and dei sire to secure by Letters Patent, is

'The malleable iron skeleton-hub and fastenings descrlhed in the specification and drawings, I
